4 Claims. (01. ie-sa) This invention relates to door stops, and itsobject is to-produce a-doo'r stop which can be made inexpensively butwhich 'is adapted to be used either on the floor or extendinghorizontally out from the wall. By the use ofmy invention such a stopcan be made very strong, and at the same time can be made of goodarchitectural appearance. I The essential featureof m y' invention isthat the stopis made in two principal pieces--an end member and a base,which are assembled together by a tongue and socket connection so shapedthat the tongue is substantially square. By utilizing a square tongue,the conformation of the sides is carried out for any one of the threepositions possible for the end member and the strains are exerteddirectly from the end member to the base.

A supplemental pinv is used simply to hold the parts assembled but nottotake up the strain.

.20 the top and the socket on the base, but a. reversal the illustrativeexamples shown in the accompanying drawing, in which Fig. 1 is aperspective view of a device embodying my invention set for use on thefloor; Fig. 2 is a plan view of the structure shown in Fig. 1 with someof the parts broken away and the hook not shown; Fig. 3 shows a slightlymodified form of deviceassembled for mounting on the wall, and Fig. 41sa plan view of the device shown in Fig. 3 with parts broken away.

Referring to Figs. 1 and 2, the numeral 10 designates the base portionwhich has an upwardly extending square column 12 in which is formed aslot indicated at 14. This 'slot is square,

that is, its depth is exactly equal to the width of the columngwhere theslot passes through, and the top is formed perpendicular to the sides.

The top of end member 15 is provided with a resilient cushion 18 made ofrubber or other desired material and has a tongue 20 which is square andis of such a size that it will fit exactly into the slot 1%. A pin 22passes partly through the a base and the tongue 20, and should beexactly centered on the squares of the tongue and slot. In this examplethe pin 22 is formed with a ring 24 at one end, in which is engaged ahook 26 which is intended to cooperate with an eye on the r door to holdthe door open when desired.

1 have found it desirable to form the tongue on In the structure shownin Figs; 3 and '4 the partsare very similar, but in-this case the base'11, instead of having plain sides, carries at its upper end,three'grooves '13, and the end member 1'7 has a'transverse ridge 19,which fits'intoone of 50 these grooves. Inthis case, as before, Idesignate the slot and tongue as square even though they are of somewhatirregular conformation 'due to thegrooves 13; In these iiguresthe' pin21 is a simple screw passing partly-through the base and the tongue' Itis preferable that the two forms of pins shown at 21 and 22 be madeinterchangeable.

It will be seen that with either form of construction when the pin isremoved, the top mem- '7 ber can be inserted either-as a continuation ofthe base as shown in Fig. 3, or pointed in either of two directionssideways as shown in Fig. 1, and other forms of pin may be utilized, butthe strains on the bumper will be transmitted di- '75 rectly from thetop member to the base without any tendency to shear through the pin,and the parts cannot change their relative position without removing thepin, so there is no possibility of their being assembled out ofadjustment.

The construction "above described not-only lends itself to highlyartistic designs, but is of great advantage inthat only one type ofbumper need be shipped to a construction job and then as the bumpers areinstalled, they can be ar- 5 ranged either for attachment on the flooror the fl baseboard Further, if at any time it is desired to supply ahook to hold the door open, it simply means substituting the form of pinshown at 22 in Fig. 1 in place of the form of pin shown at 21 in Fig. 4;The economies resulting from these ready interchanges more than overcomethe added expense of making the bumper in three parts instead of in asingle part.

What I claim is:

1. A door stopcomprising a base member and 5:3 an end member, one ofsuch members having a squared end and at least two sides substantiallyperpendicular to the end, a slot passing through such end and'sides,which slot is of a depth equal to the distance between such sides, theother 1' member having an end portion of substantially identical crosssection with the end of said first member and having a tongue extendingtherefrom of a size substantially identical with the ize of said slot sothat contact shoulders are 1 provided upon the tongued member adapted tocontact fully with the other member when said slot is occupied by, saidtongue and the end member is a continuation of, or is transverse to,said 10 base member, and a pin adapted to connect said members byinsertion on an axis centered on said tongue and slot.

2. A door stop comprising a base member and an end member, one of suchmembers having a substantially square tongue running substantially fromedge to edge and so that substantial contact shoulders are provided andthe-other a substantiallysquare slot extending to its end and sides,which slot is substantially the same size as the tongue, whereby suchmembers may be interlocked in a plurality of positions with two faces ofthe tongue serving as continuations of the faces of the slotted memberand with the contact shoulders of the tongued member fully bearingagainst the slotted member'so'that the two members cannot be movedrelative to each other without partial disengagement, and means wherebysuch disengagement may be prevented. 3. A door stop comprising a basemember, an end" member, and connective means therebetween, which includea slot provided in the end of one of said members running from side toside of longitudinally square dimensions and a tongue of substantiallyequal dimensions provided upon an end of the other member running fromside to side .thereof'and providing substantial contact shoulders uponsaid member sothat the end member and base member may be joined in threedifferent positions to give different directions to said end member byinserting the tongue into the slot, in all of which positions thecontact I of longitudinally square dimensions and an elongated endmember of substantially similar cross sectional size as said postprovided with a bumper at its outer end and a tongue upon its inner end,said tongue being of approximately equal size as said slot, said membersbeing so proportioned that substantial contact shoulders are providedupon said end member adapted to contact and totransmit strains from saidend memberto said base member directly, said tongue being adapted to bepositioned insaid slot so that the end member is a continuation of orlateral to said base member atchoice and so that, the slot I iscompletely filled, but so that the contact shoulders fully bearagainstthe base member, and means for retaining said tongue of saiden member inposition insaid slot.
